There are many kinds of thermal conductive materials, such as thermally conductive silicone sheet, thermally conductive phase change sheet, thermally conductive gel, thermally conductive silicone grease, thermally conductive insulating sheet, silicon-free thermally conductive sheet, carbon fiber thermally conductive pad, etc., each of which is used in different fields and industries. It plays an important role. With the continuous development and progress of science and technology, electronic products and high-tech equipment are developing in the direction of light weight and multi-function, resulting in dense internal parts arrangement and more precise and high-performance parts. It also leads to a very narrow internal space.
There are many factors that cause equipment to generate heat, and the main reason is that part of the energy is dissipated in the form of heat during electrical energy conversion, and most of the heat sources are small and capable power-consuming electronic components. Heat is conducted from the surface of the component to the outside, and a thermally conductive material needs to be installed on it to more effectively conduct the heat to the outside, but the internal space is narrow and there is a certain voltage, so a thermally conductive material that can be thin and insulated Yes, and thermal film can do just that.
thermal film is a silicone polymer elastomer reinforced with glass fiber as the base material. This thermal film can effectively reduce the thermal resistance between the electronic components and the radiator, and is electrically insulated, with high breakdown voltage strength, good thermal conductivity, tear resistance, etc., and can effectively avoid leakage , Breakdown and other accidents. At the same time, the thermal film has strong temperature resistance to avoid aging and deterioration due to long-term overheating.
The characteristics of thermal film are its high insulation, lightness and thinness. The thickness of common thermal film is 0.2-0.5mm. It can be used in occasions where the tolerance gap is very short. At the same time, the thermal conductive silicone cloth has tensile strength, wear resistance, Temperature resistance is relatively good; and the thermal film is insulated and can withstand higher voltages, so as to avoid that when the voltage on both sides of the insulator continues to increase, the electric charge in the insulator material is subject to the greater the electric field force, which makes it easier Lead to ionization collision, leading to the phenomenon of insulator breakdown.
